Australian Ammaroo Turquoise cabochon. Clear backing.
This cab is from the famous Tosca mine 30km North of the Ammaroo pastoral station and near the Ampilatwatja indigenous community. This mine is the only known commercial production of Turquoise in Australia and was first discovered in the late 60’s. Previously this was a phosphate mine. The mine has been permanently closed for quite a long time so these pieces are quite rare. This cab is backed with premium ultraclear epoxy- so you can see the back of the stone as well as the front.
